And S300, carrying out the writing transaction of the application according to the updating self-checking instruction, wherein the writing transaction characterizes that the first data and the second data are written into the target area respectively, and generating a return value, and the return value is a value generated by comparing the application of the intelligent card after the first data and the second data are written into the target area successively.

In some optional embodiments, after receiving an initialization instruction sent by the terminal before receiving the update self-checking instruction, the smart card initializes a first data area in the smart card to random data to obtain first data; after receiving the initialization command, the smart card initializes the second data area by a fixed number, for example, initializes the page data of the second data area to 0 or 1 to obtain second data, and the specific initialization number of the second data area is not limited herein. And ensures that the first data is not identical to the second data. Because the first data and the second data are different, the first data and the second data can be written into the target area continuously and alternately, namely, after the first data is written into the target area, the second data is written into the target area to cover the first data written into the target area, if the first data and the second data are the same, the first data is written into the target area again, then the second data are stopped to be written into, and when the target area and the second data are compared, the difference cannot be compared, namely, whether the second data are written into the target area is unknown, so that the aging test is influenced.

In some alternative embodiments, the target page of the first data write target area and the target page of the second data write target area are the same.

In some alternative embodiments, the smart card sends an initialization success response to the terminal after the initialization is completed successfully. In some embodiments, if the initialization of the first data area and the second data area of the smart card fails, the smart card sends a failure response to the terminal so as to re-receive the initialization instruction of the terminal, or the terminal performs quality detection on the smart card to obtain a quality detection report, thereby repairing the smart card. After receiving the initialization success response, the terminal generates an update self-checking instruction, wherein the update self-checking instruction comprises the maximum writing times and the writing instructions of the smart card, the smart card respectively writes the first data and the second data into the target area within the maximum writing times, and generates a first return value or a second return value after the completion of the first data and the second data.
